Letters Patent No. 110,914, dated January, 1o, 1811.

|MPROVEMENT IN WRENCHES.

The Schedule referred to in th'ese Letters Patent and part of the same.

To all 'whom it -maygconcern Be it known that I, JOHN GOODIN, of Joliet, in

the county ot' Will andin '.the State of Illinois, have heing had to the accompanying drawing and to the letters ot' reference marked thereon;A making apart of this specification. f

The nature ot' my invention 4consists in forming a wrench i-n three parts to operate as wiltbe hereinafter described.

fca'tionf v A. represents one portion of the body of the wrench, and B, the other. ABoth of' these pieces 4are east of malleable iron, and areeach provided with two jaws, one at eachend. Y The jaws a and b' are Yformed upon one ofthe pieces, while the jaws a and b are formed npon the other. The shrinks connecting the jaws are bent in the form- -represented in the drawing, and are both formed very similarly, except that the piece B lras recesses castin'itsjaws,1within which the other piece lies and slides.

In the annexed drawhw makinfr )art of this s eci- V a c C represents a right and left serew,wh icl1 passes through the elbows of the pieces A and B, and being placed longitudinally of.them, when turned t the right or left, either opens or closes `thejaws at one end of the wrench...

lVheu thel jaws waf'sepamte by the aetionof the screw C, the jaws band 1i' close or move toward ea'ch other, and the reverse.

This wrench is .very simple and durable in its cun-` sttion, and is quickly operated, as the'jaws at one end open in an inverse ratio to theclosingof those at the other.

Having thus fullydescribed my invention,

'What I claimes'new, and desire to secure by Letters Patent, is--' The pieces A and B, constructed as described, and used in'eombination with a right-and-lelt screw, O, as

and .for thepurpose set forth.

In testimony that Lelaim the foregoing GI have hereunto set my hand this 21st day of June, 1870; JOHN GOODIN.

Witnesses;

H. R. BENSON, MARTIN SHEPHERD.
